To all w/Lom'z't mag/"concern:

Be it known thatlwe, VILLIAM' Sroiiisviin,4 EDwnRD STOEBNEP., EMANUELY Swimmer., @andl DANIEL: S'ronBNnR, citizensot the United a tiill,clear, and exact description ot the invention, suchas' will enable` othersskilled in the art to which itappertains to make and' use the' saine.y y y The invention-relates to beam bracestor cultivators, and has for its object rtol pro#V vide a device ot character which may ben easily and quickly attached to the beams oty a conventional it'orm ot' `cultivator and'con-l structed in a manner whereby thebe'ains may move in a vertical longitudinal planeincident to the unevenness ot the 'groiind, and the beams at the same time braced 'in' a manner whereby side-twisting "thereof will be prevented, which side twisting of the beainsfis a common diliiculty where discs are carried by ,the beams.

A further object is to provide spring actuated pivoted deflecting arms tor detle'cting plants, such as corniiito'the `archedport-ion of the brace, and preventing the cornstalks from coming into engagement with the sharp edges ot the cultivator beams or brace.

A further object is to provide a cultivator beam brace comprising right angularly shaped members having their vertical arms in registration and connected by link members forming a parallel movable device and their horizontal arms provided with means whereby they may be secured to adjacent cultivator beams. Also to provide the lower arms of the horizontally disposed arms with right angularly shaped spring actuated members adapted to cooperate with the inner sides ot the cultivator beams for forming detlecting means t'or plants.

l/Vith the above and other objects in view the invention resides in the combination and arrangement ot parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope ot what is claimed without departing from the spirit of the invention.

Figure 3 is an enlargedftop plan view ot one ot the braces.

Referring to the drawing, the numeral l designates conventional forms of cultivator beams and 2 discs carried thereby. It-has been round that where discs are used on' cul and at thesame time the discingoperation is notainitorm; To obviate `this diliic'ulty the adjacent cultivator beams l are connected together by a brace 3.

brackets Iand- 5. Bracket-s 4 have their verticalV arms 4f in registration with; the vertical arms 5 of the brackets 5, and the armeeb ot the right angularly shaped fbrack# ets'e extend over the upper side'otL the cultivator beams l, andi. are secured'thereto bymeans oit' bolts G, which extend through'ithe arms b andthe arinsi ot thefbracletsr4 '5,

which last named arms are in horizontal positions and engage the under sides ot the beams l. It. will be. noted that the bolts G are spaced apart, therefore the device may be applied to cultivators having their beams l at various distances apart. The upper ends ot the arms el and 5 are connected together by means ot a bar 7, the ends ot which are pivotally mounted on the bolts 8. Arms t and 5a are additionally connected together by means of the segmentally shaped bar 9, the ends et which are pivotally connected at l0 to the arms la and 5a. It will be noted by providing the bars 7 and 9 having their ends pivotally mounted to the arms 4 and 5, a parallel movement may take place between the opposite brackets, thereby allowing the cultivator beams 1 to move upwardly and downwardly independent ot each other, according to the nature of the ground being worked, but at the saine time twisting of the beams 1 will be prevented. By forming the bar 9 segmentally shaped, it will be noted that plants The lbrace 13 is f disposed` may easily pass between the same, particularly corn plants, therefore the brace will not interfere with the use of the device on a straddle row cultivator.

To prevent the corn stalks or other` plants from coming into engagement w1th the sharp edges of the beams 1 and the arms 5, and to guide the stalks to positions where they will pass under the segmentally shaped bar 9, forwardly and outwardly extending pivoted arms 11 are provided, which arms are pivotally connected at 12 to the under sides of the arms 5" adjacent their inner end. Arms 11 are provided with angularly disposed arms 13, which extend outwardly and have connected thereto coiled springs 14:, the outer ends of which are connected at 15 to links 16 which are pivotally mounted on the lower ends of the bolts 6, and it will be noted, that by referring to Figure 3, the springs 14C will maintain the forward ends of the arms 11 in engagement with the inner sides of the cnltivator beams 1 and the arms 11 will guide corn stalks and other plants into a position, where they will pass under the bar 9. By providing the springs 13, the arms 11 will be maintained in engagen'ient with the inner sides of the cultivater beams 1, and the device can accommodate itself to cultivators having beams at different distances apart and of different widths, therefore the device can be applied to any conventional form of cultivator.

From the above it will be seen that a brace is provided for adjacent oultivator beams, and which brace will prevent spreading or twisting of the beams, and at the same time will allow freedom of movement of the beams in a longitudinal vertical plane independent of each other, especially when the cultivator is going over rough ground. 7 and 9 prevent the beams 1 from twisting, but at the same time allow a parallel 1nove ment of the beams 1 during their vertical movement. A

The invention having been set forth what is claimed as new and useful is 1. A plant deflector comprising spaced beams a bracket carried by the beams, pivw oted arms carried by the bracket and extending forwardly and outwardly into en gagement with the inner sides of the beams, said pivoted arms being provided with out wardly extending arms and springs co operating with the outwardly extending arms and forming means for holding the pivoted arms in engagement with the beams.

2. A plant deflector comprising spaced beams, inwardly extending brackets carried by said beams, pivotally angularly shaped levers pivoted to the undersides of said brackets, one arm of said lever extending outwardly towards the beams, coiled spring connections between said last named arms and the beams, the other arms of said angularly shaped levers extending forwardly and outwardly into engagement with the adjacent sides of the beams.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
